“…The antibacterial activity of the blank and SiO 2 NP/cotton/lycra composite fabrics against Gram-positive bacteria Staphylococcus aureus and Bacillus cereus and Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa was assessed qualitatively using the AATCC Test Method (147-1988) expressed as the zone of growth (mm) [ 18 , 35 ].…”

This study aims to develop multifunctional pile cotton fabrics by implementing different compositions of lycra yarns with different densities of the cotton fabric under study. Highly dispersed silica nanoparticles (SiO2 NPs) with small sizes—in the range of 10–40 nm—were successfully prepared and were analyzed using scanning electron microscopy (SEM). The particle size distribution of nano silica was determined via dynamic laser scattering (DLS) and measurements of its zeta potential. Cotton/lycra fabrics were treated using prepared SiO2 NPs in presence of ethylenediaminetetraacetic acid (EDTA) as a crosslinking agent. Energy dispersive X-ray (EDX) analysis and scanning electron microscopy (SEM) were used to characterize the nano-treated fabrics and assure homogeneous dispersion of SiO2 NPs on the cotton/lycra composites. Additionally, the nanoparticles were screened for their in vitro antibacterial activity against human pathogens such as Gram-positive Staphylococcus aureus and Bacillus cereus and Gram-negative Escherichia coli and Pseudomonas aeruginosa strains. The functional properties of the new composite pile cotton fabrics include excellent antibacterial, highly self-cleaning, and excellent UV protection factor (UPF) properties.

Despite their long successful use, synthetic dyes have several problems due to their carcinogenic and toxic effects. Besides providing bright colors, some natural pigments have shown notable antimicrobial activity; thus, they could be utilized as functional dyes in many applications such as making colored antimicrobial textiles. In this work, a yellow pigment produced by Streptomyces thinghirensis AF7 and has a notable antimicrobial activity was used to produce a colored antimicrobial textile. The extracted yellow pigment was subjected to a purification step using silica gel column eluted with di ethyl ether solvent. The FTIR, GC-MS and NMR analysis showed that the colorings in this type of product are due to the presence of chromopeptides. The purified yellow pigment was effectively used to dye two types of fabrics (cotton and polyester). Results showed that polyester had more affinity for yellow pigment than cotton. The stability of dyed fabrics was verified based on ISO 105-E01:2013 which demonstrated that both dyed cotton and polyester fabrics had a considerable degree of fastness to water, seawater and detergent. Moreover, yellow dyed Polyester fabric exhibited more stability against acid than yellow dyed cotton fabric, and both were unstable against alkaline solution. Finally, the yellow dyed fabrics showed antibacterial properties against S. aureus proving that the antibacterial activities of the yellow pigment could be retained when the pigment is bound to the fabric.

“…Recently dyes are now produced in a full range of colorants with no hetero aromatic diazo based colorants. Heterocyclic-based dyes are mainly derived from the diazo compounds containing five-member rings with one or more nitrogen heteroatoms, and then the rings are being fused to obtain another aromatic ring [5,6] .…”

A series of novel mono and diazothienopyrazolone dyes were successfully synthesized and characterized, the coloration performance of the prepared dyes was assessed on wool fabrics. The structures of the synthesized dyes were characterized and confirmed by making use of IR, UV, 1HNMR and C13NMR spectrophotometers with a view to determine and confirm their chemical structure. Antimicrobial activity of the dyes fabrics has been investigated, the dyeing performance of the as prepared dyes in terms of color strength (K/S), CIE lab as well as fastness properties (washing, rubbing, perspiration and light) of the dyed wool fabrics were also investigated. The synthesized dyes exhibited high and homogeneous dyeing performance, antimicrobial activity and the fastness properties of the dyed fabrics were ranging from good to excellent.
